Notice the embedded Spring-Steel reinforcement webbing. It allows the
seal-flap to be adjusted & angled to "Hug" & cover all Gaps.

Door-Gap Seal

Below...Door Closes easy from inside. No slamming, pulling and MOST
important our Seal is on the Door, it will never get damaged.

The "Spring-Steel" reinforcement channel has "Gripper" teeth to hold firmly
in place. And when your door is closed the seal is pinched between the
airframe. You can not pull the seal out when the door is closed...however applying adhesive into the
channel is recommended.
